Allowing for lower resistance values in high-reliability applications, the enhanced devices feature ratings down to 49.9ohm at ± 25ppm/C TCR and a 0.1% tolerance, and 10ohm at a 1% tolerance.
Intended for high-reliability military and aerospace applications with stringent performance requirements, the enhanced E/H resistor chips offer stable film and performance characteristics of 200ppm at + 70C for 10,000 hours. Established reliability is assured through 100% screening and extensive environmental lot testing, through which the devices have been rated for an 'R' failure rate level (0.01 % per 1000 hours).
The resistors’ all-sputtered wraparound terminations ensure 'excellent' adhesion and dimensional uniformity. Exact dimensions and clean, straight edges are produced by a precise wafer-sawing process. The E/H devices’ electroplated nickel barrier layer enables operation at temperatures up to + 150C, and their high-purity alumina substrate allows for high power ratings.
In addition to very low noise of less than -25dB and a low voltage coefficient of ± 0.5ppm/V, the non-inductive resistors feature an absolute TCR down to ± 25ppm/-C, laser-trimmed tolerances down to 0.1%, and typical wraparound resistance of < 0.01ohm.
